Cointelegraph (owned by Minergate) is not in good standing with the community. I wonder why the owner of xmrwallet.com would choose to advertise there of all places...
It probably still reach a lot of people, which is good to attract new people to get to know Monero. [edited: 1740 views of this article until now, which is not really a big number IMO] Probably better then other media news. And of course in the end it all comes to price. Maybe Cointelegraph has lower theirs due to smaller demand.
Anyway, good to see development on making using Monero easier for average user and on increasing it's utility.
